Observe the following instructions: Only operate the pumps with hoses of the specified dimensions. The maximum permissible pressure of 1 bar at the suction connection must not be exceeded. Hazardous substances must be separated out as far as this is technically possible before they reach the pump. External mechanical stresses and vibrations must not be transmitted to the pump. Only use flexible laboratory hoses for connecting pumps. The overpressure generated at the pressure port must not exceed 1 bar. The pump must not be used to suck up fluids. Lay the exhaust pipe so that it slopes downwards, so allowing condensate to flow out of the pump. Collect the condensate and dispose of it in an environmentally compatible manner. Prevent dyes exuding. Maintain a space of least 20 mm between the pump and adjacent parts in order to enable the pump to cool. CAUTION! Solid particles in the pumping medium impair the pumping action and can lead to damage. Prevent solid particles penetrating into the pump

7 Basic Safety Instructions 2.4 Hazardous Substances ACHTUNG! The operating company bears the responsibility for the use of the Diaphragm Pumps. Hazardous substances in the gases to be pumped can cause personal injuries and property damage. Pay attention to the warning notices for handling hazardous substances. The local regulations apply in foreign countries. Combustible, aggressive and explosive Gases Don t pump combustible, especially aggressive or explosive gases or vapors or operate this pump in an atmosphere containing combustible or explosive gases or vapors. Examine before switching on whether that can form gas combustible gas/air mixtures which can be promoted! Consider the regulations of the guideline 1999/92/EC. The Diaphragm Pumps are not certified according to ATEX guidelines 2014/34/EU. The Diaphragm Pumps are not recommended for pumping acidic, basic or organic vapors. Poisonous Gases Use a suitable separator when pumping poisonous or harmful gases. Prevent such substances from leaking out of the appliance or pump. Treat these substances according to the applicable environmental protection regulations. Test the strength and leak-tightness of the connecting lines and the connected apparatus. Prevent environmental poisons, e.g. mercury, getting into the pumps. Fulfil the requirements, for example: German Hazardous Substances Regulation (GefStoffV) of 01. December 2010 Regulation 2016/1179/EU (Classification, Packaging and Labelling of hazardous substances), Manufacturer's safety data sheets on hazardous substances. 2.5 High Temperatures The Diaphragm Pumps may heat up as a result of the temperature of the gas being pumped and through compression heat.

Should the user change the electrical connection, for example for fitting into a system, then this may only be performed by a electrical specialist under observance of the accident prevention regulations

9 Description Display - Vacuum Regulator The Vacuum Regulator shows pressures at below atmospheric pressure. The reference point for the gauge is atmospheric pressure. WARNUNG! Please keep in mind that the barometric pressure changes from day to day. This also changes the displayed pressure values because of latent air pressure fluctuations. 3.2 Protection measures against liquids in the pump Condensate separator (Suction side) If the possibility of penetration of larger liquid quantities, we recommend the additional installation of a larger collection vessel (eg. Woulff bottle) Cold trap (Suction side) The installation of an appropriate cold trap is required when a larger amount of steam (water, solvent) is obtained which exceeds the tolerance of the vapor pump. The refrigerant used is usually dry ice or dry ice mixture with an acetone or alcohol. Maintenance: The refrigerant must have the highest possible level in the cold trap. The rise in pressure in the connected vacuum apparatus indicates that the cold trap is saturated. For cleaning remove the cold trap and defrost. The condensate must be disposed of properly. The cool trap is, if applicable, clean with a detergent and dry. 3.3 Areas of Application The Diaphragm Pumps are intended to: Pumping and compressing neutral and aggressive gases and vapours.
